Can anyone please suggest me the code which will fix this issue? i am quite noob to php :( only good at CSS and Photoshop.

Thanks in Advance.

You can add exception handling around it, so if it fails, it does nothing.

Something like this:

foreach ($urls as $key => $url) {
    $url = trim($url);

    try {
      $html = file_get_html($url);

      $ep = $html->find('.post-container img');
      $data .= $ep[0]->src . "\n"; 
    }
    catch (Exception $e) {
        echo "Error parsing url: $url<br/>";
    }
}

Aha. file_get_html is not a built-in PHP function. Did you download the package it belongs to?
